Just trying to run a simple Win32 program (From Handmade Hero Series by Casey Muratori)

Its not a Visual Studio Project. Its just a cpp file with Visual studio C compiler in command line.

#include <windows.h>

LRESULT CALLBACK MainWindowCallback(HWND Window, UINT Message, WPARAM WParam, LPARAM LParam){
    
    LRESULT Result = 0;

    return Result;

}

int CALLBACK WinMain (HINSTANCE Instance, HINSTANCE PrevInstance, LPSTR CommandLine, int ShowCode){
    
    WNDCLASS WindowClass = {};
    
    WindowClass.style = CS_OWNDC|CS_HREDRAW|CS_VREDRAW;
    WindowClass.lpfnWndProc = MainWindowCallback;
    WindowClass.hInstance = Instance;
    WindowClass.lpszClassName = "HandmadeHeroWindowClass";

    if(RegisterClass(&WindowClass)){
        HWND WindowHandle = {};
    } else {

        }

    return 0;
}

Command Line:

/out:handmade.exe
/debug
handmade.obj
handmade.obj : error LNK2019: unresolved external symbol __imp_RegisterClassA referenced in function WinMain
handmade.exe : fatal error LNK1120: 1 unresolved externals

Tried replacing RegisterClass with RegisterClassA RegisterClassW RegisterClassEx, but that didn’t work. Win32 Docs have Visual Studio specific answers. Help
